A few of the best for me had to be when we beat Florida in OT on our way to the National Championship, when we went to legion field, where we hadn't won at in forever, scored on the first offensive play(Manning to Kent) and went on to win 41-14, and of course seeing the team hoist the National Championship trophy.
A few of the worst had to be the entire 2008 season, seeing Fulmer show up with just plain listless teams in bowl games year after year, and when Clausen and co. blew it against LSU in the SEC chmp. game in 2001.
